Can you transmute it to i16x4 instead? I'm concerned about potential issues on big-endian targets.

I've checked on the big-endian armebv7r-none-eabi and bitcasting to i16x4 and f64 generate exactly the same assembly. Unfortunately bitcasting to i16x4 causes LLVM compilation failures when only the vfp2 (or d32) target features are enabled (but works fine when the neon target feature is enabled).

In that case we should move all vector types to be under the neon feature rather than vfp2, otherwise the exact same problem will happen for i16x4.
